Panic Attacks: Why They Happen and What to Do When You Feel Like You're Losing Control

You’re at the grocery store, on the Metro, or just sitting on the couch. Suddenly, your heart starts racing. You feel like you can’t breathe. Your hands shake, your vision blurs, and a thought flashes through your mind like a bolt of lightning: “Something serious is happening to me.” It lasts a few minutes, but it feels like an eternity. And when it’s over, a new fear remains: that it will happen again.

If you've experienced something like this, the first thing you need to know is that you're not in any real danger and that you're not going crazy. Panic attacks are an intense response from the nervous system that, although terrifying, has an explanation. Understanding panic attacks—why they happen and what to do when they occur—is the first step toward stopping fearing them and starting to manage them.

What exactly is a panic attack?

A panic attack is a sudden episode of intense fear or distress that peaks within a few minutes. It is not an overreaction or a sign of weakness. It is a real physiological reaction involving a massive activation of the sympathetic nervous system—the same system that kicks in if your life were in danger.

According to the International Classification of Diseases (ICD-11) According to the WHO, panic disorder is characterized by recurrent and unexpected attacks accompanied by persistent worry about the possibility of their recurrence. The most common symptoms during an episode include rapid heartbeat, sweating, trembling, a feeling of suffocation, chest pain, nausea, dizziness, depersonalization, and fear of dying or losing control.

It is important to distinguish between an isolated panic attack and panic disorder. Many people experience one or two episodes throughout their lives without this constituting a disorder. The problem arises when the attacks recur, when you start avoiding situations out of fear that they will happen, or when the anticipation of the next episode begins to affect your daily life.

Panic Attacks: Why They Happen and What Triggers Them

There is no single cause. Panic attacks arise from a combination of biological, psychological, and contextual factors that vary from person to person. Here is what clinical evidence identifies as the main triggers.

Overactivation of the alarm system

Your brain has an extraordinary survival mechanism: the fight-or-flight response. When faced with a real threat—a car barreling toward you, a loud noise in the dark—the amygdala triggers a surge of adrenaline and cortisol that prepares you to react. The problem is that this system can go off without an objective external threat. It’s as if a fire alarm were going off without any smoke.

Accumulated stress and emotional overload

Months of work-related stress, family conflicts, unresolved grief, or simply a buildup of minor stresses can overwhelm your nervous system. A panic attack isn’t triggered by the most recent problem, but by the cumulative effect of all the previous ones. Your body has been sending more subtle warning signs for some time—insomnia, muscle tension, irritability—and panic is its way of saying, “I can’t take it anymore.”

Biological and Genetic Factors

Research suggests that there is a genetic predisposition. If a close family member has had a panic or anxiety disorder, you are more likely to experience it. Imbalances in neurotransmitters such as serotonin and norepinephrine also play a role, as does increased sensitivity to changes in blood CO₂, a factor that several studies have linked to a greater likelihood of triggering attacks.

Sensitivity to Anxiety

This concept, developed by researcher Steven Reiss, refers to the tendency to interpret the physical sensations of anxiety as dangerous. If, when your heart starts racing, you automatically think, “I’m going to have a heart attack,” you’re fueling the cycle of panic. It’s not the sensation itself that triggers the full-blown attack, but rather the catastrophic interpretation you make of it.

Substance Use

Excessive caffeine, alcohol, cannabis, and other substances can act as direct triggers. Cannabis, for example, can cause panic attacks even in people who previously used it without any problems.

The Vicious Cycle of Panic: Why It Keeps Happening

The most frustrating thing about panic attacks is that the fear of having them is precisely what keeps them going. Here’s how it works: you have an attack, and the experience is so unpleasant that you start constantly monitoring your body. Any slightly stronger heartbeat, any feeling of dizziness, becomes a warning sign. That hypervigilance generates more anxiety, and that anxiety produces the very sensations you fear. It’s a self-perpetuating cycle.

Added to this is avoidance. You stop going to the movies, driving on the highway, or staying home alone. Every situation you avoid brings you immediate relief, but in the medium term, it reinforces the message that “there’s danger out there.” Your world gradually shrinks. And that’s the real problem: not the attack itself, but how you reorganize your entire life around the fear that it will happen again. If that avoidance extends to open spaces, public transportation, or crowds, it can lead to agoraphobia, something we discuss in detail in Psychologist for Agoraphobia in Madrid: Regain Your Freedom.

What to Do During a Panic Attack: Specific Techniques

When you're in the middle of an attack, logic goes out the window. That's why it's a good idea to have a clear plan that you've practiced before. Here are some techniques backed by clinical research that you can use in the moment.

Slow Diaphragmatic Breathing

Hyperventilation is one of the symptoms that causes the most panic, because it intensifies dizziness and tingling. Breathing slowly—inhaling for 4 seconds, holding your breath for 2, and exhaling for 6—activates the parasympathetic nervous system, which acts as a natural brake on the stress response. It’s not about taking deep breaths, but about breathing slowly. A prolonged exhalation is the key.

The 5 Senses Technique (Grounding)

When you feel yourself drifting away from reality, anchor your attention in the present moment. Name 5 things you can see, 4 you can touch, 3 you can hear, 2 you can smell, and 1 you can taste. You don’t have to say them out loud. Just naming them in your mind takes your brain out of threat mode and brings it back to the present moment.

Remember that it will pass

A panic attack rarely lasts longer than 10 minutes. The peak intensity doesn't last. Telling yourself, "This is anxiety, not danger, and it will pass," may seem simple, but it breaks the cycle of catastrophic thoughts. You are not in danger. Your body is reacting as if you were, but you’re not.

Don't run away from the situation if you can help it

Running away from the place where the attack occurs reinforces the association between that location and danger. If possible, stay put. Use breathing and grounding techniques. When the panic attack subsides in the same place where it began, your brain registers that the location was not dangerous. This is a form of natural exposure that reduces the likelihood of future episodes.

What to Do in the Long Term: Panic Attacks and How to Prevent Them

Managing an attack when it occurs is necessary, but not sufficient. The real solution lies in addressing what causes and perpetuates them. This is where psychotherapy plays a central role.

Cognitive-Behavioral Therapy (CBT)

CBT is the treatment with the strongest scientific evidence for panic disorder. A meta-analysis published in The Lancet Psychiatry (2017) confirmed that CBT is significantly more effective than a placebo and comparable to medication, with the advantage that its effects are better maintained over the long term. The treatment includes psychoeducation about panic, restructuring of catastrophic thoughts, and interoceptive exposure, which involves deliberately inducing sensations similar to those of a panic attack (exercising, spinning in a chair, briefly hyperventilating) so that your brain learns that these sensations are not dangerous.

Complementary Approaches

Depending on the individual, other approaches can be very helpful. Acceptance and Commitment Therapy (ACT) offers an interesting shift in perspective: instead of fighting anxiety, the goal is to change your relationship with it. Learning to observe your sensations without automatically reacting to them reduces the power they have over you. In each case, it is the professional who determines which approach is best suited to the situation and the person’s needs.

What surprises people most when they start therapy is discovering that the problem they thought they had is rarely the real problem. Many people come in saying, “I have panic attacks,” and as the process unfolds, they discover that underneath it all lies chronic, unaddressed stress, an unresolved relationship conflict, or a way of managing emotions they learned long ago that no longer works for them.

Myths and Facts About Panic Attacks

When to Seek Professional Help

An isolated panic attack does not always require treatment. But if the episodes recur, if you’ve started avoiding certain situations, if the fear of another attack is influencing your decisions, or if you feel that anxiety is taking over your daily life, consulting a licensed psychologist is the most sensible step to take. Don’t wait until the problem becomes chronic.

One of the questions I hear most often at the start of therapy is, “How long will it take for me to get better?” There’s no honest answer that doesn’t start with “it depends on each individual’s process.” What I can say is that panic disorder is one of the anxiety conditions that responds best to psychological treatment. Many people experience significant improvement in the first few weeks when they commit to the process.

Frequently Asked Questions About Panic Attacks

Why do I have panic attacks for no apparent reason?

Panic attacks can occur without an obvious trigger because they result from accumulated stress, a biological predisposition, or a sensitivity to anxiety. Your nervous system reacts as if there were a real threat, even when there isn't one. A psychologist can help you identify the factors contributing to your specific situation.

Can a panic attack kill me?

No. Although the symptoms are very intense and may resemble those of a heart attack, a panic attack does not cause physical harm or put your life at risk. It is an anxiety response, not a cardiovascular emergency. If this is your first time experiencing it, going to the emergency room to rule out any underlying medical causes is reasonable and can give you peace of mind.

How long does a panic attack last?

The most intense phase usually lasts between 5 and 10 minutes. Residual symptoms such as fatigue, muscle tension, or restlessness may last a little longer, but the peak intensity does not persist indefinitely.

What is the difference between anxiety and a panic attack?

Anxiety is a sustained state of worry that can last for hours or days with moderate intensity. A panic attack, on the other hand, is an acute, intense, and brief episode that occurs suddenly with very pronounced physical symptoms such as a racing heart, shortness of breath, and depersonalization. If you’d like to assess your level of anxiety, you might be interested in our article on Anxiety Test: What It Really Measures and How to Interpret It.

Can panic attacks be cured?

Panic disorder is one of the anxiety disorders that responds best to psychological treatment. Cognitive-behavioral therapy has been shown to be highly effective, according to the American Psychological Association (APA), with long-term effects. Talking about “cure” is complicated in mental health, but you can learn to manage anxiety so that it no longer controls your life.

What should I do if someone next to me has a panic attack?

Stay calm, speak in a calm voice, and remind them that what they’re feeling is anxiety and that it will pass. Don’t force them to do anything or simply tell them to “calm down.” Be there for them without pressuring them, and, if necessary, help them breathe slowly.

Do I need medication for panic attacks?

Not always. Psychotherapy is just as effective as medication for panic disorder and is associated with lower relapse rates. In some cases, it may be helpful to combine both approaches, but medication should always be evaluated and prescribed exclusively by a psychiatrist.

Can I have panic attacks while I'm sleeping?

Yes. Nighttime panic attacks occur during sleep and wake you up with intense symptoms of anxiety. They are not related to nightmares, but rather to the activation of the nervous system during certain stages of sleep. They are treated the same way as daytime panic attacks.
